You're receiving this bug because the package in Summary has produced _FORTIFY_SOURCE related warnings indicating the presence of a sure overflow in a static buffer.

Even though this is not always an indication of a security problem it might even be. So please check this out ASAP.

By the way, _FORTIFY_SOURCE is disabled when you disable optimisation, so don't try finding out the cause using -O0.

Thanks,

Patch to ripmime-1.4.0.9.ebuild to address buffer overflow

This patch adds a sed call to rewrite the offending snprintf to use the correct length.  Before applying it, you must also apply the ebuild patch posted in bug #334593 as attachment #244793 [details, diff] (which in turn applies new patch file attachment #244791 [details, diff]).
